    This Week on the Breadboard: The LPD Sixty8 (with some mods)

    I like the simplicity of the 4-knobber. Bass - for me, no more than 10 o'clock, but I think I prefer it at zero. Treble - to the max. I breadboarded CDB version, but for now I'm sticking with the original (which I did quickly in 0805).

    This Week on the Breadboard: Phase 90

    Sigh... it works, but I made such a embarrassing mistake. I fired it up and found there was no phasing at the output. The LFO is working, and the voltages look fine. I poked around with an audio probe, and everything seemed fine, but the modulated signal wasn't reaching Q5. There was a signal at...

    Jump Drive schematic?

    It'll probably be quicker and easier if you trace it yourself :). But keep trying, maybe Robert will finally show mercy. :)

    Tyco Brahe Ocavia Diode Lift Mod

    There's no connection to GND. Just insert switch between diode and transformer (or diode and pin 3 of the potentiometer).

    Tyco Brahe Ocavia Diode Lift Mod

    Only one diode. With the switch open there's only fuzz, no octave.

    Stuff you wanted to know but were afraid to ask

    It's when you set the Tone knob at noon ;) But it's also a printing technique that simulates grafients, continuous colors/shades of gray with small dots (of various sizes).

    Bring out yer Diptrace

    I think I'd run the trace from the 1N5817 to the 100u and run all the supply traces from the capacitor. Something like this (red is an alternative route)

    Biasing JFets for Chop Shop

    I don't remember what voltage I set. Test it in the 4-6.5V range, see how the sound character changes, and choose the setting that suits you best.

    Biasing JFets for Chop Shop

    Measure the voltage on pin 1 (marked in red). It should be the same as on pin 3 (marked in green). Full CCW means minimum voltage (max sag). Bias should be set as if there was no SAG potentiometer at all (full CW).

    Scabbard inductor value

    I wasn't referring to Tayda, actually. I was referring to using a jumper instead of an inductor. If you plug these values into an LC filter calculator, you'll get the filter's GHz cutoff values.

    EXAMPLE Developing a custom pcb for Daisy Seed - Funbox

    Now I have it installed. make -C libDaisy worked without errors, same with make -C DaisySP. Now I get errors when trying to compile to bin files. pluto.cpp: In function 'int main()': pluto.cpp:926:8: error: 'class daisy::DaisyPetal' has no member named 'InitMidi' 926 | hw.InitMidi()...

    EXAMPLE Developing a custom pcb for Daisy Seed - Funbox

    I agree.. Now I have everything in my user directory. It's better, but still a bit of a struggle. $ make -C libDaisy make: Entering directory 'C:/Users/root/FunBox/libDaisy' mkdir -p build/Drivers/Patched/STM32H7xx_HAL_Driver/Src arm-none-eabi-gcc -mthumb -mfloat-abi=hard -mfpu=fpv5-d16...

    EXAMPLE Developing a custom pcb for Daisy Seed - Funbox

    Until now, I've been playing with pre-made bin files downloaded from Releases. But I wanted to try Mercury, which isn't available as a bin file. So... I installed Git, downloaded everything I needed, and replaced the daisy_petal files. The first problem occurred with the next step - I ran Git...

    6 band EQ potentiometer version C100 value

    There is enough space to easily fit a 6.3mm diameter cap. Just pay attention to the pinout raster - it looks like 2.5mm.

    Contact with copper substrate

    Not necessarily. It could be the GND solder pad, so it's normal for there to be a connection to the surrounding copper layer. Look at the solder pad marked in red. There are small bridges (like spokes) connecting the solder point to the copper (called thermal reliefs). Take a good look around...
